SMART METERSADVANCES IN WATER METER TECHNOLOGY

NORTH PENN WATER AUTHORITY

COMMON CURRENT METER TYPESMECHANICAL

• Positive displacement

• Nutating disk

• Oscillating piston

• Multijet

• Singlejet

• Compound

• Turbine

• Fire Service

COMMON CURRENT METER TYPES

UltrasonicElectromagnetic

MAGNETIC AND ULTRASONIC METERSHOW DO THEY WORK?

Magnetic

• Faraday’s law

• Magnetic field is generated

• Water passing through creates small electric

current that is proportional to velocity of flow

• Current is measured and converted to number

Ultrasonic

• A pair of transceivers positioned in tube

• Ultrasonic pulses up and downstream

• Time difference of the pulses is computed into

the flow rate

MAGNETIC AND ULTRASONIC METERS

• As of now AWWA manual M6 does not include a standard for either

• AWWA manual M33 does include and describe both

• Both come in a wide range of sizes

• Mag- 1/10” – 120”

• Ultrasonic – ¼” – 360”

• Popular manufacturers have common residential, commercial, industrial sizes

• No moving parts

• Can accurately measure very low flows

MAGNETIC AND ULTRASONIC METERS

• No or very low head loss

• No loss of accuracy over time

• Testing

• Mag – follow manufacturer test procedures

• Ultrasonic – no special testing procedures

• Battery has a limited life

• Most manufacturers claim 20 years

MAGNETIC AND ULTRASONIC METERS

• A 2016 Utah Water Research Lab study was released showing the accuracy differences between

mechanical and Mag/Ultrasonic meters.

• This study showed that the “electronic” meter more accurate at flows ¼ gallon and less.

• Low flow accounts for large part of residential usage

• Will record overall usage more accurately

• A plus is the usual digital display that gives better resolution than analog

SO, IS MY MECHANICAL METER NOT SMART?

• MAYBE. DEFINITELY MAYBE

• A mechanical meter can be a smart meter with the right register

• Encoder registers allow transmission of information to the reading device

SO WHAT MAKES THESE METERS SO DARN SMART ANYWAY?

IT’S ALL ABOUT THE INFORMATION

• What information does the meter get for me?

• Depending on the brand:

• Leak/Broken Tube/Continuous flow

• Tamper/Empty Pipe

• Reverse flow

• No flow

• No communications

THE ENDPOINT

• Most brands of radio read are compatible with other brands of meters

• Reads the meter multiple times a day

• Transmits to collector one to several times per day

• Data sent

• Intermittent usage

• 15 minutes to hourly

• Alerts/Alarms

• Leak

• Tamper

• Reverse flow

• No flow

THE ENDPOINT

HOW DO I OBTAIN THIS INFORMATION?

Now for a brief discussion on meter reading

HISTORY OF METER READING

• Direct reading

• Meter readers

• Customer post cards

• Remote read registers – late 1960’s

• GTR

• Touch Pads

• AMR – 1970’s – Automated Meter Reading

• Telephone lines

• Low power RF

HISTORY OF METER READING CONTINUED

• AMI - Advanced Metering Infrastructure -Fixed base

• A few ways to get the readings and other available information

• RF

• Collectors/Antennas

• On tanks

HISTORY OF METER READING CONTINUED

• AMI - Advanced Metering Infrastructure -Fixed base

• A few ways to get the readings and other available information

• RF

• Collectors/Antennas

• On tanks

• On buildings

• Radio towers

HISTORY OF METER READING CONTINUED

• Satellite

• Excellent for remote areas

• Good for sparsely metered areas

• No cell network available

• No infrastructure for utility

HISTORY OF METER READING CONTINUED

• Cellular

• Must have cell network

• Good for sparsely metered area

• Data fees from cell provider

HISTORY OF METER READING CONTINUED

• RF Is most the common in PA

• Usually line of sight

• RF signal can be easily blocked by:

• Geography

• Cast iron pit lids

• Structures

• Distance restrictions require multiple collectors

• Health concerns from radio frequency waves

RF HEALTH CONCERNS

• The American Cancer Society has done research and recently released a short report that states:

• “RF radiation doesn’t have enough energy to remove charged particles such as electrons

(ionize), and so is called non-ionizing radiation. Non-ionizing radiation has enough energy to

move atoms in a molecule around or cause them to vibrate, which can lead to heat but it can’t

damage DNA directly.”

• Same type of RF waves that cell phones produce

• Meter pit

• Takes transmitter away from house

PRIVACY CONCERNS

• Common concerns are:

• Personal information

• Billing information

• Usage patterns

• Offer an alternative

• Offer an opt out solution

• Defeats the purpose of the smart meter, but satisfies the customer

TO AMR or AMI? THAT IS THE QUESTION

• AMR

• Meter reader needed

• After the fact review of:

• Usage

• Alarms/alerts

• No reads

• Com failures

• Assets on the street

• Reactive

• AMI

• Infrastructure needed

• Daily review of:

• Usage

• Alarms/alerts

• No reads

• Com failures

• No assets on the street

• Proactive

A VERY IMPORTANT REASON THAT AMI IS THE WAY TO GO…

• NOBODY HAS EVERY BEEN

CHASED OR BIT BY A DOG

WHILE READING A METER

THROUGH AN AMI SYSTEM.

I HAVE THE “SMART METER”. NOW WHAT DO I DO WITH IT?

SOFT COMPONENTS OF THE AMI

• RNI

• Regional Network Interface

• Analytical Software

• This is a valuable tool to remain proactive

• Shows alerts and alarms

• Develops usage history

• Shows incremental reads and usage

• Graphs and charts

• Utility can host or pay hosting fee

BENEFITS TO THE UTILITY

• On demand data

• Saves windshield time for final reads

• Customer high bill complaints

• Reduce meter reading costs

• Builds usage history on all accounts

• Compare time periods

• EDU audits

BENEFITS TO THE UTILITY

• Non-revenue water

• Zone/virtual metering

• Daily system output

• Problem meters are reported daily

• Repairs can be completed prior to billing

• The software does the analyzing, not the CSR or billing clerk

THE DASHBOARD

Two months of raw history

Weekly and yearly usage graphs

CUSTOMER BENEFITS

• Utility receives alerts/alarms daily – can act quickly to resolve

• Not monthly or quarterly

• Can notify the customer when leak begins

• Customer engagement software

• Web portal

• Email/text alerts

• DIY how to videos

THINGS TO CONSIDER

• Cost – initial investment

• Meters

• Endpoints

• Infrastructure

• Software

• Maintenance contracts

• Hosting

• Upkeep

THINGS TO CONSIDER

•But the ultimate questions are:

•Are you ready to be more efficient?

•Are you ready to be proactive rather than reactive?
